IMPROVEMENT IN HARNESS-MOTION FOB. LOOMS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES SCHILLING, cot' Auburn, in the county ofCayuga, and State of New York, have invented a new 'and usefulImprovement in W0ollen-Looms; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and' use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich-4 Figure 1 is aside elevationof a loom-frame, showing my improventin machinery attached.

' Figure 2 is an end view of the same.

Figure 3 is a detached view of my improvement in another position ofmovement. Figure 4 is a section of the reverse cranks a a', taken in theline :v z, iig. 1. l Similar letters of reference indicate like parts.

This invention relates to a new and improved mechanical device foreffecting the shed-motion in powerlooms for weaving woollen goods, andconsists inthe combination and arrangement of the sliding-plate,adjustingscrews, cranks, adjustable pitman-rods, piston-rods, and the'standard G, as will be hereinafter more fully described, whereby a moredirect action upon the piston-rods to work the jacks is governed by thesubstitution of a few large crank-joints and connections for a number ofsmall ones, and the consequent saving of friction and wear and tearwhich involve expense and loss of time in working the loom. A furtheradvantage results from my improvement, by which the motion is easier,and tender yarns can be woven with less liability to strain agnd breakthan with the ordinary shed-motion. Y

A represents the skeleton-frame of a loom, in which is hung' thehorizontal driving-shaft B t work the jacks. On one end of the 4shaft Bare attached the reverse cranks a a', connected by pitman-rods b b',with thc vertical piston-rods c c', which have their connections-made inthe usual waywith the top and side jacks cfa woollen-loom for liftingthe harness and producing the shed-motion. The cranks a a and the pitmenb b are made adjustable, to alter the stroke of the pistons and changethe shed-motion as desired, as shown in the drawings; and the rods c care {itted Vto slide up and down in a suitable side standard, C. On theend of the wrist-pin d of the outside crank a is attached a short arm,e, for connection with the rod of the pattern chain,

instead of the connection on a separate crank-plate, as usual. The cranka is slotted near its ends d, to receive the adjusting-screws which fitinto and retain in any desired position a plate, g, upon theface of thecrank. This plate is provided with a number of holes to receive the endsof the screw for the purpose of adjustingl it to regulate the throw ofthe pistons.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- The combination and arrangement of the sliding-plateg, adjusting-screwsf, cranks a a', adjustable pitmanrods-b b',piston-rods c c', and standard C, substantially as described for thepurpose specified.

The above specification of my invention signed by me this 12th day ofNovember, 1866.'
